' all toiwmit mag concern:

' Be it known that we, EDWARD B. Hr.ss, of

the borough State of.

of Manhatta-mcity, county, and I\ and State of New York, citizens of the United States of America, have invented a certain new and ,useful- Improvement in o Type-Writing Machines, of which 'the following is a specification. i

This invention relates to Visible writing niachines', particularly to front strike machines, wherein the type bars are actuated bykey-lever-operated links movable toward the front of the machine to pull the'type bars to the printing point.

' The invention is comprised in the organization hereinafter set forth in detail, and is an improvement upon the construction shown in Our Patent No. 881,511 ofSeptember 18,

In the accompanying drawing: Figure 1 is a plan view, with some of the type bars omitted, of so much of a front strike type- 2 5"writing machine as is thought to be desirable to illustrate the invention; Fig. 2, a frontwiew with some parts omitted and some broken away; Fig. 3, a vertical longitudinal section showing the left hand side plate of the machine; Figs. 4, 5,- 6 and 7 are detail views showing the different lengths of key levers and type bar actuating links with which they areponnected; and Fig. 8, a detail plan showingthe jointed type bar actuating links at the center of the machine. V

The platen 1 is mounted 1n carnage 2.

. 3 is the carriage shift rail by which the carriage is elevated for upper case printing. Between the side plates 1, 4 of the machine is supported a vertically disposed type bar segment 6, of appropriate construction, in

. which are pivoted thetype bars 7 that nornially lie in a substantially horizontal positionwith their heads toward the front of the machine and upon a rest 8. Each type bar has eonnected to its heel, or the projection beyond its pivot, a draw'link 9 that extends forwardly under the assemblage of type bars and at itsfront end has a hlnge connection with a shorter link mounted to rock about a ew York, and Lewis G. MYERS, of the borough of Brooklyn, county of Kings,

Specification of Letters Patent. Patented J a121, 13,1914. Application filed-February 25, Hill. Serial Ro.610,682 1 13 which are pivoted on a common trans vei-se pivot rod 'li-disposed belowIthe-asr semblage of type bars. I z 15 indicates the universal bar ;movable fore-and-aft of the machine as the Royal Standard'typewriting machine and from/the type bar operating links 9 there extend draw links 16. having hooked ends that-embrace the universal bar. Surroundingjach link 16 .is a coiled spring 17 having its'ff-ront 'end connected "toe clip b which the link 16fis connected to the type ar link}! and its rear back plate pf'thefiinachine. I M V.

The special features of eonstruction'orarrangement embed ring the present invention end connected in a plate 18at't-ached tothe axes of the links 12 shall be maintainedgin a straight transverse line across the front of the machine. The part. 19 is slotted on its are as follows: T e keylevers 13 comprise under face to form bearing slots tor'the re spective lever-links 10, 10. The partitions or flanges 21 have bored orcut in them transversely of the machine in astraight line a seat 21' for a common pivot rodi-ll that forms the axis or bearing for ,all the front lever-links 10, 16. This rod isin'serted' endwise, aperturesjflI"; being formed j in one or both side platesfor that purpose. :The front lever-links 10, 10 "extend rearwardly, those in the center being at right angles to the axis 11 and those at .e'achside being, with gradually increasingangle', turned toward the center of themaehine. The whole a ssemblage 1 of lever-links jis divided into two series, the links, of one series being-marked 10 and the shorter links of the other series being marked 10, These longer and shorter levers are arranged'in alternationgi' As seen in Fig. 8, this results inrastaggering offthe type bar operating links v9. The latter may vbe merely hooked into apertures in the forconnections between -the levei links and the clearance.

ends of the front lever-links there is ample The key levers are straight and lie throughout their length in parallel straight lines at right angles to their axis let. The shortest and next longer key levers whose finger pieces a, Z), are in the two upper or most rearward rows in the key board are connected by vertically disposed links 12 to the longer frontlever-links l; and the nextlonger and the longest key levers, whose finger pieces 0, d, are in the two lower or most forward rows in the key board, are connected with the shorter front links 10'.

As may be seen from Fig. 3, the longer front lever-links 10 .are inclined rearwardly and downwardly from their fixed axis 11 and the shorter lever-links 10f are-similarly inclined but have a somewhat greater downward inclination from a'horizontal plane. All the short lever-links 10' are inclined downwardly at, a uniform angle: and all the. longer lever-links are also inclined *downi ardlylat a different, but uniform,

angle. 1T0 procure substantially uniform depth of depression and approximately uniform .fitouch of all the finger pieces of the key board, the following plan is adopted. The shorter key levers, whose finger pieces a are in the rear row of the key board, are each connected to one of the longer leverlinks 10 (Fig. 4) by a link .12 extending upwardly from the corresponding key lever, the points of connection of the substantially vertical link to the lever-link 10 and to the key lever being such as to afiord a desired extent of depression of the finger piece a to I I throw the type bar to the printing point.

The next longer key levers whose finger pieces I) are inthe second row from the rear in the key board are also eachconnected (Fig. 5 to a long lever-link by a link 12; but the point of connection of the latter link'to the link 10 is nearer the fixed axis'll than is the corresponding substantially vertical link connection of the shortest key lever. In both instances the points of connection of the vertically disposed links 12 with the-key levers are at the same distance from the fixed axis 14 of the key levers.

and from the axis of the key lever at whichthe connections of links 12 are made is such as to afford a depth of depression of the finger piece the same as that for the finger pieces a, b, and also substantially the same touch.

Fig. 7 shows one of the longest key levers others and substantially the same touch. -.3

Fig. 8 shows in plan the arrangement of the two series of links '10, lOinalternation, the links shown being those at the center of the machine. This staggering of the ends of the lever-links 10', 10 with reference to a straight transverse line afiords ample room forthe hooks or other means of engagement on the draw-links 9 by which they are attachedto the lever-links l0, 10"-so that -in the operation of the machine one'cannot ins terfere or collide with another.
